Ukraine says rebels firing rocket launchers again

KIEV, Ukraine (AP) — Separatist rebels in the east of Ukraine have resumed the use of rocket launchers that should have been withdrawn under a February peace deal, Ukrainian military officials said Tuesday.

The army said in a statement that rebels fired Grad rockets Monday evening at the government-held town of Avdiivka, which lies on the fringes of the main rebel stronghold of Donetsk.

There has been a recent uptick in clashes along the front separating government and rebel forces. Speaking at an investor conference in Kiev, President Petro Poroshenko warned that the resumption of full-blown war is a perennial threat.

"War could start at any moment, but we are ready to do everything possible to dispel any room for doubts or retreats," he said.

Oleksandr Motuzyanyk, military spokesman for the Ukrainian presidential administration, said one soldier had been killed and 14 injured during the past day's unrest. He gave no details on where casualties had been sustained.

"The geography of cease-fire violations by militia has broadened. For the first time this month, the enemy has deployed the Grad system against our servicemen,"Motuzyanyk said.

Eduard Basurin, the spokesman for separatist forces in Donetsk, in turn accused Ukrainian forces of dozens of cease-fire violations. Organization for Security and Cooperation in Europe observations on craters created by recent impacts in the rebel-held village of Nova Marivka confirmed that Ukrainians troops had been using 152-mm artillery shells, Basurin said.

More than 6,000 people have died and a million have been displaced by the conflict that has raged over the past year.

A cease-fire tortuously negotiated by France, Germany and Russia in Minsk, the capital of Belarus, requires the warring sides to pull back their most powerful arms by distances over 50 kilometers (30 miles).

Responsibility for checking whether the deal is being implemented lies with the OSCE, but its special monitoring mission said late Monday that its monitors have been prevented by rebels from visiting a location where heavy arms have allegedly been deployed.

For the third time in four days, the rebels have prevented the mission "from freely accessing the eastern part of Shyrokyne," the OSCE said in statement.
